I really like the concept here: giving your heart to the ocean. For some reason it reminds me of that scene in "Titanic" where Rose, as an old lady, drops her necklace into the ocean at the end. Even though I'm not a fan of the movie, I like that scene.

This line of the poem really stands out: "a last memory to keep in the water." It's so sad, but so lovely at the same time.
